I'd assume Linus has much better quality of life than Gates or Ellison. He's pretty well off, but doesn't have to suffer from recognazibility and billionaire problems.
Having your children abducted and held for ransom. People wanting to kill you because they think you put microchips in their bodies through a vaccine. Not knowing if people you meet are just trying to extract money or publicity from you.
The first 2 are solved by top notch security which billionaire money can buy (and then some)
The last "problem" honestly it's more of a compliment , and besides a billionaire's pockets are so deep that the extraction of money via social interactions are small leaks which are not only acceptable but should be again taken as a compliment.
It's a mistake to assume that all people are socially anxious just because one is posting on HN or reddit.
Recognazibility is lit and so are billionaire problems (btw what billionaire problems? Failing to win the America's Cup? G650ER mantainance fee?)
